TOP ROLL FOR SPINNING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 395,938, dated January 8, 1889.

Application filed September 10, 1888. Serial No, 284,970. (No model.)

To {LN 11:71am it 7210 concern/.-

Be it known that l, EDWARD RlGHl, a citizen ol: the United States, residing at Von cester, in the county of \Votcester and State of Massachusetts, have invented certain new and useful Improvements in Top Rolls for Spinning-Machines, of which the following, together with theaccompanying drawings, is a specification sutticiei'ltly t'ull, clear, and exact to enable persons skilled in the art to which this invention appertains to make and use the same.

My present invention relates to the construction of the top roving delivering-rolls which are employed in wool-spinning machines such as described in my Letters Patent No. 370,940, and other similarmechanism; and the object of my invention is to provide top rolls adapted for the purpose specified, which shall be in j' tjg'llt, of strong and durable constriwtion, and which can be man ufacturcd with facility and at comparatively small cost; also, to afford a construction which will give practical uniformity in the size and weight olt the rolls and facilitate constructive duplication throughout 'an unlimited series without requiring special care in litting or the necessitvot' turning or grinding off the peripheral surface to render the rolls (amcentric, uniform, and in balance on their axles. These objects I attain by rolls, the parts of which are constructed and combined in the peculiar manner hereinafter explained.

In the drawings, Figure 1 is a perspective view of my improved top roll for wool-spinning machines. Fig. 2 is a longitiulinal cen tral section of the same. Fig. 3 is an end view. Fig. l is a side view of the arbor separate. Figs. 5 and ti show details of the cupshaped parts separate, and 'l i 7 and 8 are sectional views showing the arrangement of these top rolls on the spinning-machine.

My improved top roll is composed of a journal, axle, or arbor, A, provided at each end with a roller-lwad, ll, formed of cup-shaped ylinders 71 and c, which are respectively punched and drawu'l'rom thin sheet metal in the manner of seamless die-drawn ferrules and fitted together and combined with the axle-bar in the manner illustrated.

The axle A is formed'with a central bearing-surface, a, and with ends that are reduced or turned off to form shoulders (l and e, as shown in Fig. t. The peripheral surface of the roller-head B is formed by the cylindrical shell or thimble I), which is punched and drawn up from sheet metal to the size required for the length and diameter of the roll, and a hole, (1, is formed through its end or disk axially concentric with the periphery and of a size that will fit close upon the arbor A ad jacentto the shoulder (Z. The second cylindrical cup-shaped shell, 0, is of similar structure but of lesslength and diameter,

and is fitted tightly within the end of the cylinder b. The end disk of: the cup 0 is provided with an axially-concentrichole, e, that will fit closely onto the end of the arbor against the shoulder c. these sheet-metal cups is jn-elferably about t-liree-sixty-fourths of an inch, and such cups or shells being drawn in suitable dies are all of a uniform shape and dian'leter of their respective kinds.

\Vhen putting the rolls together, the cylindrical parts I) and e are slipped or driven onto the ends of the arbor A, the rim of section 0 fitting tightly within the end of section b and each fitting snug upon arbor A against its respective shoulder. The end of the arbor A is then riveted or upset at E, thus firmly bind ing the parts together in a secure and rigid manner, the adjoining cups, 1) c, forming a hollow cylindrical head or roller, B, at each end of the arbor with the hearing or journal (6 between the two. These rolls when in use on the spinning-machinc are held in proper relation to the bottom roll, F, by a supporter, I, that is attached to the roving-beam or car rier K, and which embraces the axle-journal a, as illustrated in Figs. 7 and 8, the mechanism operating as describml inmy l'letters Patent No. 370,8-t0, above rei'crredto.

I am aware that hollow rolls have heretofore been employed and that rolls connected in pairs are in use, and it will therefore be understood that I do not broadly claim such features in a roll of other construction than that illustrated and described.

Vhat I claim as of my invention, and do The thickness of consisting of the axiom-inn A, having upon each of its ends a roller composed of two cup 0, fitted upon the arbor :igninst tho shoulder 0, with its peripheral. riin fitting Within Sheet-metal (lie-drawn cups, 7) and c, fitted one and supporting the rim of Th0 cup I), and ro- Within the other and eonoontrically fixed upon said arbor, snbsi'mitially as described.
